昆明长水国际机场砂页岩（∈2 d）残积红土的粒度成分研究

摘要

论述4种化学分散剂对昆明长水国际机场砂页岩(∈2 d)块状红土粒度成分的分散作用，分析比较不同分散剂分别在不同浓度条件下对红土颗粒分析试验的作用规律，获得了最佳分散剂浓度及相应的粒度曲线和粒度成分，并确定了昆明长水国际机场砂页岩(∈2 d)块状红土粒度成分特征值，为长水国际机场对红土成因、红土粒度成分分析测试、红土综合性质研究应用提供了一种研究思路和研究方法。%This paper discusses four kinds of dispersants which have dispersed effect on sand shale (∈2d) lumpy laterite in kunming changshui international airport,analyzing and comparing different dispersants′disperion of laterite particles analysis test under the condition of different concentration, get the best dispersant concentration curve and the corresponding size and particle size composition, and identified sand shale (∈2 d) laterite block size composition eigenvalues in kunming changshui in-ternational airport, to provide a research ideas and research methods for the genesis of laterite in cahngshui International airport,the analysis of laterite,particle size and the application of the inte-grated nature of laterite.
